SNAPPIN ROLL.

Application filed October 10, 1924. 'Serial No. 742,862.

To all 'whom t may concern:

Be it known that I, JOHN E. MALMBERG,

a citizen of the United States, residing at Lee, in the county of Lee and State of Illinois, have invented new and useful Improvements in Snapping Rolls, of which the followingis a specication. A This invention relates to new and useful improvements in corn snapping rolls and more particularly to that type of roll which is used for stripping the husks from the corn when either in a green or ripe state.

Considerable objection has been found in the well known snapping roll in use at the present time in view of the fact that the husks and stalks have a tendency to become wound or entangled with the ends of the snapping rolls and clogging the machine and, it is therefore the main obj ect of my in-l vention to provide means whereby to prevent this clogging of the rolls through the action of the stalks and husks.

Another object of my invention is the provision of means which can be applied to snapping rolls in use at the present time or formed integral with any particular type of roll and includes the application of a cam to each individual roll lfor preventing the husks and stalks from winding or entangling with the smooth portion of the rolls.

With the above and other objects in view the invention consists in the novel features in construction, the combination and arrangement of parts hereinafter more fully set forth, pointed out in the claim and shown in the accompanying drawings in which Fig. 1 is a plan view of a pair of snapping rolls arranged in their proper operative positions and illustrating the application of my invention.

Fig. 2 is a detail plan view of one end of a roll.

Fig. 3 is a longitudinal section taken on the line 3-3 of Fig. 2.

Fig. 4 is a transverse section taken on the line 4--4 of Fig. 1.

Referring now more particularly to the drawings it will be noted that in Fig. 1 I have illustrated the relative positions of a pair of snapping rolls generically indicated by the numerals 1 and 2, each roll being provided with the usual spiral rib 3 which ter- 'ininate a short distance from the end of the roll or in spaced relation with theoperating gears 4. In machines of this character it has been the tendency of stalks, husks, corn ears and the like to becomewound or entangled with this portion of the roll adjacent the rib and the end or operatinggear and in thismanner clogging up the machine and in a great many instances shelling the corn from the cob. In order to prevent this clogging in shelling I have formed on each of the rolls two cam members 5 and 6, the cam members 5 being arranged at the end of the rolls adjacent the operating gears 4, while the cams 6 are disposed at a remote position with respect to the operating gears and out of transverse alignment with the cams 5 and also disposed upon the opposite side of the roll with respect to the cams 5 thus completely illing all space adjacent the ends of the rolls where this clogging usually takes place. It will be noted in Fig. 1 that between the inner end of the cam 5 and the spiral rib 3 there is considerable space which permits the stalks, husks and the like to lodge therein and in order to remove them to prevent clogging of the rolls the cam 6 during the rotation of the rolls will engage within this space and have a tendency to remove all particles becoming lodged therein.

From the particular arrangement of the cams 5 and 6 as illustrated in Fig. 1 the cams, during the rotation of the roller will be brought into substantial longitudinal alignment as shown in Fig. 4 thus completely filling all space between the spiral rib 3 and the operating gears 4 so that no space remains in which the stalks and the like can become lodged.

Attention is directed to the fact that the cams 5 on each of the rolls is so positioned that when the rolls are in an operative position these cams are-"disposed in alignment with each other and this arrangement is also carried out with the relative positions of the cams 6.

It is a well known fact that in a great many instances the tall stalks of corn have a tendency to be moved upwardly through the snapping rolls and in order to prevent the uppermost portions of thesestalks from entering between the rolls and clogglng them at the upper ends thereof, the relative positions of the cams 5 and 6, during the rotation of the rolls will have a tendency to break or snap these stalks so that they will drop downwardly from the rolls and not be guided in between the same and c log them during the operation of themachnie.

similar manner and in Mfthe/1furtherconstruction of snapping rolls of this character the cams may be readily cast integral 'with the body of the rolls soithatwhen'the rolls are` placed in their correct operative position with respectzptothe machine-togwhehthey arenapplied the cams Will be. so 4.arranged that during-v the rotation offithefrolls they will readily cooperatein the-.manner above set fortlrsoas to eliminate the clogging` and. filling of .,thefsnapping.; rolls jat. the upperv ends thereof.;

While Iifharefshown and described., the;- preferred `form of my s invention f I .wisha it f to be understood that Various changes and alterations mayv be carried out' during the manufacture of the Same Without departing from the spirit of the invention or the scope of the appended 'clainr Having thus described my invention what Iolaim is The combination With a plurality of snapping rolls arranged'in parallel relation and spaced from each other, of cams arranged upon opposed sides of said rolls and extendingrlongitudinally `thereof .but rout of transverse axial'aliglunentrelative tof the other andlrthewams onvtlieadjlacent rolls being disposed in longitudinal' alignment at the y passing point of saidfcams.;
